Description

A pressurized hemostatic device for liver trauma

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a pressurized hemostatic device for liver trauma.

Background technique

The liver is the largest solid organ in the human body. Liver trauma accounts for about 20% of abdominal trauma. It is a relatively common abdominal injury. According to the 6-level grading method for liver injury by the American Academy of Trauma Surgery (AAST), injuries above grade III That is severe liver trauma, the mortality rate is over 50%, and the mortality rate is as high as 80%-90% when combined with hepatic vein or retrohepatic inferior vena cava injury. The most thorough treatment for liver trauma is to resect the damaged liver segment or lobe, which can effectively stop the bleeding and avoid complications such as infection and bile leakage that may occur later. However, severe liver trauma is often combined with other organ injuries, and even pathophysiological changes such as hypothermia, acidosis, and coagulation dysfunction occur, resulting in unstable vital signs. Coupled with the uncertainty of the injury site, primary liver resection is often difficult to implement. Especially in grass-roots hospitals or battlefield conditions, the more feasible method is to debride the wound, ligate and suture the obvious blood vessel and biliary tract stump, use gauze or bandage to stop bleeding, and quickly transfer to a qualified hospital for follow-up treatment. However, due to coagulation dysfunction under severe trauma conditions, the treated liver wound may still ooze blood continuously, and the compressed gauze and bandage will be displaced during the transfer and evacuation process, which may cause the wounded to bleed again and die.

The method of wrapping the liver wound with mesh and suturing the perihepatic ligament is one of the currently recognized methods that can achieve a better effect of compression and hemostasis. The published "23 Cases of Severe Liver Trauma Treated by Mesh Wrapping Surgery" ("Chinese Literature of General Surgery", Volume 6, No. 2, April 2012) disclosed the use of the mesh wrapping method, usually square The mesh was trimmed to a suitable shape according to the injury site and scope. First, the "U" shaped mesh was wrapped around the left liver. The upper end of the mesh behind the liver was fixed to the diaphragm on the left side of the retrohepatic inferior vena cava, and the posterior proximal end of the left liver was 1/2 3. Suture and fix the diaphragm on the left side of the inferior vena cava, and fix 2/3 of the distal end to the retroperitoneum; the other end of the "U"-shaped mesh is fixed to the upper diaphragm on the left side of the inferior vena cava, and the diaphragm surface is connected to the falciform ligament, liver The round ligament was fixed with polypropylene suture, and the visceral surface was cut into an arc to bypass the first porta hepatis. When wrapping the right liver, fix the trimmed mesh on the right hepatic ligament and peritoneum to make a mesh sleeve, suture and fix the proximal 1/3 of the proximal end of the right liver to the lower diaphragm on the right side of the retrohepatic inferior vena cava, and the distal part behind the right liver 1/2 to 2/3 were not fixed; the mesh was sutured and fixed to the upper diaphragm on the right side of the superior inferior vena cava above the liver, and the polypropylene thread on the diaphragm surface was fixed to the edge of the mesh on the left side of the falciform ligament.

The mesh wrapping method achieves the effect of compression and hemostasis by fixing the mesh in multiple places, but there are the following problems: (1) The mesh wrapping method requires a group of medical personnel to stop the bleeding after the laparotomy, and another group of medical personnel according to the injury. Cutting the mesh at the site will increase the operation time and waste intraoperative resources; (2) During the operation, the liver needs to be fully dissociated and sutured in multiple places to fix the mesh, which reduces the operation efficiency and increases the intraoperative risk; (3) " "Medium cutting" and suturing operations are relatively random, which may objectively cause package "mismatch" and uneven pressure. Whether the cutting is appropriate and whether the fixation is really limited by the experience of the surgeon, the operation is relatively complicated and easily affected by human factors The effect of compression on hemostasis.

There is a V-shaped gap 6 on the visceral surface of the sleeve body. When the right side is covered with the right liver, the hilar blood vessels and biliary tract can pass through the sleeve body 1 through the V-shaped gap 6. The positions of the absorbing pressurized dry trauma hemostasis sleeve on the right side are defined according to the position of the liver. The sleeve diaphragm surface layer 11 corresponds to the diaphragm surface of the liver, and the sleeve body visceral surface layer 12 corresponds to the liver visceral surface. The cuff opening 2 of the side cuff is defined as the left side of the cuff, and the direction of the left and right lobes of the liver is defined as the outside of the cuff. Since the hemostasis of the liver is mainly aimed at the left and right lobes of the liver, the lengths of the two sides of the oval edge line 3 of the visceral surface layer 12 are different, and the longer side corresponds to the outer side of the sleeve body 1, which is used as the sleeve sewn by the edge line.
